My voice slots are full or I have fewer after a downgrade. Which voices should I keep?

Open My Voice and check which voices you still use and how many slots you have. If a downgrade screen asks which voices to keep, select them carefully before confirming. Unselected voices will be deleted. Follow the instructions shown for voices marked API. If deleting your last website voice leaves a blank voice, you can prepare a new voice in that slot. Deleting a voice is not a way to reclaim training characters.
